How Much Does It Cost to Repair a Chimney?
£200 – £1,800
per job
Chimney repairs cost between £200 and £1,800 depending on the type of work required. Minor repointing of the mortar joints is at the lower end; replacing failed lead flashing, fixing defective flaunching around the chimney pots, or rebuilding a damaged chimney stack are more involved jobs that push costs higher.
Average cost
£200 – £1,800
per job
Prices vary by region, property type and tradesperson. Always get at least two quotes.
What affects the price?
Type of repair - repointing costs £300-£700; lead flashing replacement costs £500-£1,200; chimney stack rebuild costs £1,000-£3,000+
Chimney height - taller chimneys are harder and more time-consuming to work on safely
Scaffolding - scaffolding is almost always required for chimney work and adds £600-£1,500
Brick and mortar matching - for older properties, sourcing period-matched bricks and lime mortar adds to material costs
Labour vs materials
Labour accounts for 50-60% of chimney repair costs. Roofers charge £150-£250 per day; scaffolding is usually hired separately and quoted independently.
Repair or replace?
If a chimney stack is severely deteriorated, leaning, or has widespread brick spalling, a full rebuild may be more cost-effective than attempting to repair and repoint a structurally compromised stack. Get a structural opinion before committing to extensive repointing work.
